  • Page 90: B Description Of The Function

    Description of the Function The following describes the outline and the direction for the measurement features and other func- tion of PFX2511, charge/Discharge System Controller. Description of the measurement function The PFX2511 equips the high-speed, a 24-bit delta-sigma analog-to-digital converter (ADC). It enables to perform a wide range of the measurement in 60 V / 50 A without switching the range with a resolution of 100 μV / 100 μA in high-speed and high-accuracy.
  • Page 91 Description of the Function Measurement for the operation of pulse discharge When in the state of pulse discharge operation, the measured value of 1 ms is acquired as well as measurement of the normal operation. As for the pulse voltage measurement, the measurement is executed by the pre-specified pulse.
  • Page 92 Description of the Function In this case, the calculation of average current is adding the integration of the actual measurement pulse current value until reaching to the unit time and the pulse time width. And the average current value can be calculated in division by the unit time from the added value when reaching at the unit time.
  • Page 93 Description of the Function Unbalance detection function (only when an OP01-PFX is installed) This function measures the voltages of all the cells in the object under measurement, and detects the maximum and minimum cell voltages. When the unbalance voltage (the difference between the maximum and minimum cell voltages) exceeds the set value, an alarm occurs and the output is turned off.

    This is useful when you want to evaluate a low voltage range, when you want to perform a charge/ discharge test on a single cell, or in similar situations. For the bias power supply, you can use variable-voltage power supplies such as the Kikusui PAS series, PWR series, and PAG series or fixed-voltage power supplies.
